A cable anchor assembly for facilitating ready anchored connection of cables to components while protecting the cables from external forces and from moisture. The assembly includes a plurality of plates slidably engageable along a rail for facilitating relative movement between the plates. Each plate has an engaging edge that defines a portion of a formable collar in which a cable is receivable. A fixture, such as a rubber boot, is placed over a section of the cable and, with the plates separated, the cable section is placed between the formable collar portions, whereupon the plates are brought into sliding edge-to-edge contact with each other to enclose the cable section and boot. With the plates in contact, a securing mechanism is operated to maintain contact between the plates. In a preferred embodiment, the boot is configured to create a substantially water-resistant seal between the cable section and the movable plates.

To flash a hot gas vent pipe, representatively a chimney pipe, extending upwardly through a roof opening, a tubular sleeve having vertically extending spacer members interiorly secured thereto, with upper ends projecting above the upper sleeve end, is concentrically placed around the chimney pipe and anchored to the roof. A rubber boot is then placed around the sleeve and secured to the roof. Finally, a storm collar is downwardly telescoped onto the chimney pipe and rests on the upper end of the sleeve spacer members. Vertical cooling passages are defined between adjacent spacer member pairs, and through their interiors, and have upper exit portions communicating with the storm collar interior.

Anti-skid protrusions 26 and 27 are formed on the inside of a rubber boot 20 which fits on the smooth external surface of an electrical connector housing 10. Since the connector housing 10 has no molded supports for the boot, production cost is reduced.

The invention relates to a double guidance type tensile anti-overturn shock-insulation rubber boot, which includes an upper connection plate, a lower connection plate and a boot core body, wherein a pair of bidirectional sliding assemblies on two sides of the boot core body is arranged between the upper connection plate and the lower connection plate; and each bidirectional sliding assembly includes an X-direction sliding pull plate, a Y-direction sliding pull plate, and a shearing force insurance pull ring connecting the X-direction sliding pull plate and the Y-direction sliding pull plate, wherein the X-direction sliding pull plate is glidingly matched on the upper connection plate, and the Y-direction sliding pull plate is glidingly matched on the lower connection plate. The pair of bidirectional sliding assemblies is arranged between the upper connection plate and the lower connection plate, so that the boot is not limited when generating horizontal displacement, and the boot core body generates horizontal displacement deformation to reduce the damage to a building; and when a pull force is generated in case of an earthquake or other conditions, the bidirectional sliding assemblies are limited in the vertical direction and no relative displacement is generated, so that the tensile anti-overturn function is achieved.

A face seal is provided with a constriction ring around a rubber boot that constricts the normal outward bulging of the flex section of the rubber boot as it folds and tries to roll forward over itself during axial deflection. The constriction caused by the constriction ring provides for increased frictional hysteresis during compression and decompression of the boot flex section. This increased hysteresis increases the dampening capacity of the seal design and, therefore, reduces undesired vibrations and seal noise generation.

The invention provides a fashionable rubber boot having photochromic property in appearance, a coating for the fashionable rubber boot and a preparation method thereof. The fashionable rubber boot comprises a boot body, a boot sole and a boot heel. The surface of an external rubber layer of the integrally formed full-rubber boot including the boot body, the boot sole and the boot heel is impregnated or coated with one or more layers of photochromic coatings, is bake-dried by a baking oven and then is impregnated or coated with one or more layers of gloss oil. The finished product photochromic rubber boot is very bright-colored and beautiful in appearance and has a very good visual effect. The effect is incomparable compared with the effect after coloring agent pigments are added in a rubber compound. In addition, fluorescent pigments can be also added in the photochromic coating, so that the fashionable rubber boot is more bright-colored and beautiful in appearance under the condition of natural light, has a better visual effect, can also attract the more attention of people, improve the rate of second glance of the product and further improve the fashion effect. In addition, the fashionable rubber boot is easy to find, and the photochromic property of the rubber boot can be further improved when light is sufficient, so that the fashionable rubber boot is more bright-colored and beautiful.

An underwater light includes a high intensity lamp placed in an enclosure that allows for easy lamp replacement in case of breakage or natural failure. Electrical wires are soldered to a metal fitting on the lamp. The metal fitting is received in a plastic nipple and the space between the fitting and nipple is filled with a sealant, leaving the ends of the wires exposed. The wires are connected by water proof wire nuts and the end of the lamp is enclosed by a rubber boot and an end cap. When the lamp burns out, it is easily replaced by fishing the light out of the water, removing the rubber boot to expose the wire nuts. The wire nuts are removed and the old lamp discarded. A new lamp is installed in reverse order.

A porous solid lubricant includes a lubricating component, and a resin component. The lubricating component is a solid material made porous by foaming, and is occluded in the resin. A bearing or a constant-velocity joint has the above porous solid lubricant sealed therein. Since the lubricating component is occluded in the resin while foaming the resin component, the lubricating component can be slowly exuded through molecules of the resin due to deformation of the flexible resin under external force such as compression, expansion, bending and twisting. The amount of lubricating oil retained is larger than the amount of oil retained in pores by mere impregnation. Thus, such a bearing which has a long life, can be operated at a high speed, and can be manufactured at a low cost. Also, such a constant-velocity joint has a long life and has a rubber boot less likely to be damaged.

In a steering device 10, the upper side portion of a rubber boot 120 is fixedly fitted on a case outer cylindrical component 41 of a cable case 39, and the lower side portion of the rubber boot 120 is fixed to a dashboard 100 of a vehicle body 14 over the entire circumference thereof. Thus, the case outer cylindrical component 41 can be secured against rotation more firmly compared with a prior art steering device wherein such a case outer cylindrical component is fixed at two portions thereon by means of a wire of a V-letter shape. Further, the problem attendant on the wire of the V-letter shape in the prior art steering device no longer arises even in the car models wherein the case outer cylindrical component 41 and the dashboard 100 are relatively far from each other. That is, it can be realized to secure the case outer cylindrical component 41 of the cable case 39 against rotation relative to the vehicle body 14 even in any car model.
